【摘要】 针对大牛地气田低孔低渗、地层能量低的特点,研究了全程拌氮水基瓜胶压裂液体系。压裂液性能评价表明,该压裂液具有滤失小、流变性好、配伍性好、易返排、对岩心基质渗透率损害低的特点,现场推广应用取得了良好的效果。更多还原

【Abstract】 A new waterbased guar fracturing-fluid system,mixed with nitrogen gas during the whole injection,was developed to apply in Daniudi Gasfield with low porosity,low permeability,and low producing energy.Performance Evaluation of the fluid system shows that the fluid system has characteristic of low filtration,good rheological property,good compatibleness,easy flowback,and low damage to the permeability of rock matrix.Through the generalization and application,the new fracturing fluid system has taken good effect in the daniudi gasfield.更多还原
